Quartz movements
The ambient temperature affects the precision of a
quartz movement, which will be between – 0.3 and
+ 0.5 second per day.
If you have a quartz watch the electrical power is sup-
plied by a battery. After 12 to 18 months of use (with
the exception of watches with lithium batteries) the
voltage in the battery may drop suddenly and cause
your watch to stop. Some models have a battery end-
of-life function. The seconds hand will start to jump
every 4 seconds. If this happens we recommend that
you replace the battery immediately, because once the
battery runs down totally it may damage your watch.

replaced immediately in order to reduce the risk of
leakage and consequent damage to the movement.
